Definitions

  • a cycloidal gearbox is a modern, compact transmission element providing a possibility of achieving big gear ratios.
  • the cycloidal gearbox has a high effectivity, high torque overload capacity, long service life, low noisiness, low weight and small built-in dimensions.
  • a disadvantage of all prior art cycloidal gearboxes consists in that they have a realtively big axial dimension. This dimension is a consequence of their construction, where on the back side of a gearbox an input shaft is arranged, while on the front side an output shaft is arranged with the necessity of seating of the input shaft, and if need be even a seating of the output shaft in bearings, what is evident e.g. from DE PS No. 28 35 973, which is incorporated into this description as a reference.
  • Such an arrangement of a gearbox does not allow its direct coupling, without a seating of its own, to a driven, ev. driving unit.
  • FIG. 3 is a plan view of a cycloidal gearbox in a partly transversal section
  • New constructional arrangement of a gearbox according to the invention is in comparison with prior art cycloidal gearboxes in its axial direction many times shorter, up to four to six times, the output shaft being replaced by a driven body 11 in a form of a rotating disc, which is seated with the help of a special bearing 12 in the case 7 of said cycloidal gearbox.
  • This feature predetermines it for direct coupling to a driven mechanism, without its special seating, especially for driving of different cylinders, crane crabs winches, mortar mixers, crushers, breakers, forming and assembling automatic machines, as well as for driving gears of manipulators, handling equipments and robots.
  • It is suitable for step-up gear, e.g. through arranging it between a propeller and a driven generator of a wind power plant, where in this special case the driving part 1 is driven, output part of a gearbox, while the driven body 11 is a driving, input part of a gearbox.
